Parker 25SFAN17SXZ High Flow Plug Coupling 3/8 Mnpt

Product Description

The PARKER 25SFAN17SXZ is a high flow pneumatic plug coupling designed for compressed air systems requiring reliable, low-restriction connections. Constructed from steel with a threaded MNPT connection, this plug mates with compatible high flow couplers to deliver consistent airflow at working pressures up to 300 psi. The 3/8-inch thread size and 3/4-inch body diameter make it suitable for medium-bore pneumatic lines where flow efficiency is a priority. Licensed professionals and experienced tradespeople in industrial, commercial, and heavy-duty shop environments rely on this type of coupling for tool connections, air distribution manifolds, and pneumatic circuit assemblies.

This plug coupling is suited for compressed air applications across manufacturing, automotive service, construction, and general industrial environments. It is intended for use in pneumatic systems operating within a temperature range of -4 degrees F to 212 degrees F, making it appropriate for standard indoor and outdoor compressed air service. The high flow interchange design reduces pressure drop across the connection point, supporting tools and equipment that demand higher volumetric airflow than standard interchange couplings provide.

Key Features

• High flow design minimizes pressure drop for air tools and pneumatic equipment
• Steel construction provides durability in demanding shop and industrial environments
• 3/8-inch MNPT thread for straightforward integration into standard pneumatic plumbing
• Rated to 300 psi maximum working pressure
• Operating temperature range of -4 degrees F to 212 degrees F
• 3/4-inch body diameter with 0.69-inch hex for wrench installation

Compatibility

Designed for use with high flow interchange pneumatic coupler bodies accepting a 3/8-inch MNPT plug. Consult system specifications to confirm coupler body compatibility before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system plumbing. Depressurize and lock out the air supply before connecting or disconnecting any coupling components. Apply thread sealant appropriate for pneumatic service to the MNPT threads before installation and tighten using an appropriately sized wrench on the hex flats. Do not exceed the rated maximum working pressure of the system or the fitting.
